[wasm] Provide better stack traces for asm.js code For the asm.js to WASM pipeline, the current stack traces only show low-level WASM information. This CL maps this back to asm.js source positions. It does so by attaching the asm.js source Script to the compiled WASM module, and emitting a delta-encoded table which maps from WASM byte offsets to positions within that Script. As asm.js code does not throw exceptions, we only store a mapping for call instructions. The new AsmJsWasmStackFrame implementation inherits from WasmStackFrame, but contains the logic to provide the source script and the position inside of it. What is still missing is the JSFunction object returned by CallSite.getFunction(). We currently return null.
